Answer:
Is there supposed to be a photo of what you are asking, if so please edit your question and place the photo. I have placed an explanation and an exapmle for you tho... hope it helps.
Step-by-step explanation:
1/8 of an inch is equal to 0.125 of an inch, so you know it's length to at least 0.01 then you must pick the nearest multiple of 0.125.
If you are using reactions, find the common denominator of 1/8 and the fraction you are using, divide your measured numerator by a new numerator of 1/8, and that's how many 1/8s you have.
Example
measure: 0.56 inches
Nearest 1/8: 4
4/8= 0.5, therefore 0.56 is 0.06 away from 4/8, but 0.065 away from 5/8.
Measured: 5/7
Nearest 1/8: 6
Common denominator gives 7/56 and 40/56. 40/7 gives 5.71, therefore you have 5.71 1/8s, which would round to 6.
